贝叶斯优化器为了得到c(x)的全局最优解,首先要采样一些点x来观察c(x)长什么样子,这个过程又可以叫surrogate optimization(替代优化),由于无法窥见c(x)的全貌,只能通过采样点来找到一个模拟c(x)的替代曲线,如图3所示: 图3 采样的点与替代的曲线 得到这个模拟的/替代的曲线之后,我们就能找到两个还算不错的最小...
Bayesian Optimization(BO)是对black-box函数全局最优求解的一种strategy。具体的 是一个定义在 上L-Lipschitz连续的函数,我们想要找到 的全局最优解: 这里我们假设函数 是一个black-box,对于这个black-box,我们只能观测到有噪声的函数值: 其中 ,也就是零均值高斯分布。于是整个优化目标可以变成:找到一系列的 使得...

\(\partial\) In (16), n signifies the number of iterations. The learning rate is represented by α, while the term represents the parameter vector. Additionally, the loss function evaluated over the training set is denoted by \(\nabla E({\partial_n})\). Within the Adam optimization cont...
Bayesian optimization and Lipschitz optimization have developed alternative techniques for optimizing black-box functions. They each exploit a different fo
